STATE assets sold off on the cheap by Tories could be renationalised “without compensation,” Jeremy Corbyn’s campaign said at the weekend.

The warning to big business profiteers came as the leftwinger’s economic plan was endorsed by 41 leading economists, including former Bank of England monetary policy committee member David Blanchflower.

The group said Mr Corbyn had not advocated extreme measures, defending his opposition to austerity as “mainstream economics.”

The leadership frontrunner has already pledged to nationalise utility companies alongside rail franchises as they come up for renewal.

And his election agent John McDonnell was quoted in yesterday’s Observer indicating that the policy could extend to assets being flogged off by the current government — including the Royal Bank of Scotland.

“Let’s also make it absolutely clear to any speculators in the City looking to make a fast buck at the taxpayer’s expense that if any of these assets are sold by Osborne under their value, a future Corbyn-led Labour government will reserve the right to bring them back into public ownership with either no compensation or with any undervaluation deducted from any compensation for renationalisation,” said the veteran leftwinger.

The Con-Dem coalition came under fire for its sell-off of Royal Mail, which skyrocketed in value during its first days on the stock exchange.

The criticism for the move, which included a report from a key parliamentary select committee, was thought to have encouraged the shelving of the proposed privatisation of the Land Registry.
